i-stop
The i-stop function automatically stops the engine when the vehicle is stopped at a traffic light or stuck in traffic, and then restarts the engine automatically to resume driving. The system provides improved fuel economy, reduced exhaust gas emissions, and eliminates idling noise while the engine is stopped.
Engine idle stopping and restarting
-
After parking the vehicle, make sure that the ignition is switched OFF. There is the possibility of the vehicle moving if the vehicle is parked while i-stop is operating.
-
The i-stop indicator light (green) turns on under the following conditions:
-
When engine idling is stopped.
-
-
The i-stop indicator light (green) turns off when the engine is restarted.
(AUTOHOLD operation turned off and When not using Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)/Traffic Jam Assist (TJA))
-
Engine idling stops when the brake pedal is depressed while the vehicle is driven (except for driving in the R or M position second gear fixed mode) and the vehicle is stopped.
-
The engine restarts automatically when the brake pedal is released with the selector lever in the D or M position (not in second gear fixed mode).
-
If the selector lever is in the N or P position, the engine does not restart when the brake pedal is released. The engine restarts when the brake pedal is depressed again or the selector lever is shifted to the D, M (not in second gear fixed mode) or the R position. (For the purposes of safety, always keep the brake pedal depressed when shifting the selector lever while engine idling is stopped.)
(When the vehicle is stopped by the MRCC with Stop & Go function/TJA stop hold control)
-
When the vehicle is stopped by the MRCC with Stop & Go function/TJA, engine idling stops and continues to be stopped without depressing the brake pedal.
-
When the accelerator pedal is depressed or the RES switch is operated, while the vehicle is stopped by the MRCC with Stop & Go function/TJA, the engine will automatically restart if the selector lever is in the D/M position (not in second gear fixed mode).
(When the vehicle is stopped by the AUTOHOLD function)
-
When the brake pedal is depressed while the vehicle is being driven and the vehicle comes to a stop, the i-stop function will operate and continue to operate even if the brake is released (except when driving in the R or M position second gear fixed mode).
-
The engine restarts automatically when the accelerator pedal is depressed with the selector lever in the D/M position (not in second gear fixed mode).
-
If the selector lever is in the N or P position, the engine does not restart when the brake pedal is released. The engine restarts when the brake pedal is depressed again or the selector lever is shifted to the D, M (not in second gear fixed mode) or the R position. (For the purposes of safety, always keep the brake pedal depressed when shifting the selector lever while engine idling is stopped.)

-
The battery power is depleted.
-
The hood is opened.
-
The driver's seat belt is unfastened and the driver's door is opened.
-
The accelerator pedal is depressed with the selector lever in the D or M (not in second gear fixed mode) position.
-
The selector lever is shifted to the R position.
-
The selector lever is shifted from N or P position to D or M (not in second gear fixed mode) position.
-
The steering wheel is operated with the selector lever in the D or M (not in second gear fixed mode) position.
-

-
The steering wheel is operated.
Selector lever is operated while engine idling is stopped
If the selector lever is shifted from D or M (not in second gear fixed mode) position to N or P position while engine idling is stopped, the engine does not restart even when the brake pedal is released. The engine will restart if the brake pedal is depressed again or the selector lever is shifted to the D, M (not in second gear fixed mode), or R position. (For the purposes of safety, always keep the brake pedal depressed when shifting the selector lever.)
If the selector lever is shifted from the D or M (not in second gear fixed mode) to the N or P position, and the driver's seat belt is unfastened or the driver's door is opened, the engine restarts.
Battery terminals have been disconnected
Engine idling may not stop right after the battery terminals have been disconnected. In addition, if the battery is replaced, the i-stop functions must be verified. Consult an Authorized Mazda Dealer.
